    Here is what I am thinking about doing
    My ISP provides me with 3 public IP addresses
    I want to get a Cisco cable modem (UBR) and a Cisco switch to connect to my
    ISP

    It should be able to get all 3 IPs from the ISP and route each to a Cisco
    switch right?
    I am thinking about doing ISL trunking for each private NAT network from the
    cable modem to the switch
    and have 3 sets of ports on the switch have there own subnet with there own
    gateway to the WAN with there own public IP

    Can the IOS on the cable modem get more that 1 IP address and NAT those to
    the switch with ISL or 802.3q layer 2 signaling ?
